Again thanks lots of great info how about high octane gas always thought for old valves and such was bad but for 200 mile total trip would it help or hurt the engine might as well absorb all the info you even got me thinking about the pistons and cams although I wanted to see how many miles I could pull out of the stock engine as of now 66,000 on engine when I had my 79 chevy with 350 engine had well over 200,000 on it and the buyer drove it away
Thanks again
Dave
